Abstract
OBJECTIVE To compare, using a unified approach, standardized estimated fetal weight (EFW) trajectories from the second trimester to birth and birth-weight (BW) measurements in in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) pregnancies obtained after frozen-thawed vs fresh blastocyst transfer (BT). METHODS This was a secondary analysis of a prospective longitudinal cohort study performed at the Fetal Medicine and Obstetric Departments of San Raffaele Hospital in Milan, Italy, from January 2016 to December 2020. Eligible for inclusion were singleton viable gestations conceived by autologous IVF/ICSI conception after fresh or frozen-thawed BT that underwent standard fetal biometry assessment at 19-41 weeks and had BW measurements available. All ultrasound assessments were performed by operators blinded to the employment of cryopreservation. Patients with twin gestation, significant pregestational disease, miscarriage, major fetal abnormalities and use of other types of medically assisted reproduction techniques were excluded. EFW and BW Z-scores and their trajectories were analyzed using general linear models (GLM) and logistic regression with a unified modeling methodology based on the Fetal Medicine Foundation fetal and neonatal population weight charts, adjusting for major confounders. Differences between prenatal EFW and postnatal BW centiles in the two groups were assessed and compared using contingency tables, χ2 test and conversion of prenatal to postnatal centiles. RESULTS A total of 631 IVF/ICSI pregnancies were considered, comprising 263 conceived following fresh BT and 368 after frozen-thawed BT. A total of 1795 EFW observations were available (n = 715 in fresh BT group and n = 1080 in frozen-thawed BT group; median of three observations per patient). EFW and BW < 10th centile were significantly more frequent in the fresh than in the frozen-thawed BT group (P = 0.003 and P < 0.001, respectively). EFW and BW > 90th centile were significantly more frequent in the frozen-thawed vs fresh BT group (P = 0.034 and P = 0.002, respectively). GLM showed significantly decreasing EFW Z-scores with advancing gestational age (GA) in both groups. The effect of GA was assumed to be equal in the two study groups, as no significant interaction effect was found. Smoothed mean EFW Z-scores from 19 weeks of gestation to term and smoothed mean BW Z-scores were both significantly higher in the frozen-thawed compared with the fresh BT group (EFW Z-score, 0.70 ± 1.29 vs 0.28 ± 1.43; P < 0.001; BW Z-score, 0.04 ± 1.08 vs -0.31 ± 1.28; P < 0.001). Mean smoothed EFW Z-score values in the frozen-thawed vs fresh BT groups were 1.01 ± 0.12 vs 0.60 ± 0.08 at 19-27 weeks, 0.36 ± 0.07 vs -0.06 ± 0.04 at 28-35 weeks and -0.66 ± 0.01 vs -0.88 ± 0.02 at 36-41 weeks. Mean smoothed BW Z-score values in the frozen-thawed vs fresh BT groups were -0.80 ± 0.14 vs -1.20 ± 0.10 at 28-35 weeks and 0.22 ± 0.16 vs -0.24 ± 0.14 at 36-41 weeks. Assessment of EFW and BW concordance showed a significantly greater rate of postnatal confirmation of prenatally predicted small-for-gestational age (SGA) < 10th centile in the fresh compared with the frozen-thawed BT group (P < 0.001), whereas the rate of postnatal confirmation of large-for-gestational age (LGA) > 90th centile was significantly higher in the frozen-thawed vs the fresh BT group (P < 0.001). Logistic regression analysis showed that the smoothed rate of EFW < 3rd centile was about 6-fold higher in the fresh vs frozen-thawed BT group (P < 0.001), whereas the smoothed rates of EFW 90th -97th centile and > 97th centile were nearly double in the frozen-thawed compared with the fresh BT group (P < 0.05 and P < 0.001, respectively). CONCLUSIONS Robust novel unified prenatal-postnatal modeling in IVF/ICSI pregnancies after frozen-thawed or fresh BT from 19 weeks of gestation to birth showed non-divergent growth trajectories, with higher EFW and BW Z-scores in the frozen-thawed vs fresh BT group. The mean EFW Z-scores in both IVF/ICSI groups were greater than those expected for natural conceptions, being highest in the midtrimester and decreasing with advancing gestation in both groups, becoming negative after 32 weeks in the fresh and after 35 weeks in the frozen-thawed BT group. Mean BW Z-scores were negative in both groups, with lower values in preterm fetuses, and increased with advancing gestation, becoming positive at term in the frozen-thawed BT group. IVF/ICSI conceptions from frozen-thawed as compared to fresh BT presented increased rate of LGA and reduced rate of SGA both prenatally and postnatally. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Abstract
Study question
Does post-thaw blastocyst culture time prior to transfer influence the live birth rate in frozen-thawed embryo transfer cycles?
Summary answer
Our study revealed that different culture times of frozen-thawed blastocysts prior to transfer does not influence live birth rate.
What is known already
Several studies demonstrated a significantly increased clinical pregnancy rate after a frozen-thawed embryo transfer (FET) compared to a fresh embryo transfer (ET). FET reduces the risk of ovarian hyperstimulation syndrome without facing adverse effects of supraphysiological hormonal levels over endometrial receptivity. However, little is known on the effect of post-thaw embryo culture duration prior to transfer on live birth rate in FET cycles. Recent findings described an improved blastocyst morphological grade after a 20-22h post-thaw culture. Of note, the overnight culture of non-ideal morphology thawed blastocysts prior to transfer resulted in an enhanced live birth rate.
Study design, size, duration
We compared the live birth rate of patients undergoing FET after a short blastocyst culture time (2-4h) prior to transfer to that of patients in whom thawed blastocysts were transferred after a long embryo culture time (20-22h). Frozen-thawed transfers of blastocysts vitrified at Day 5 and subsequently thawed were evaluated. Only transfers of single blastocyst were included.
Participants/materials, setting, methods
The study was conducted at the Infertility Center – Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico, Milan. We included couples with indications for IVF cycles who underwent frozen-thawed blastocyst transfer procedure on the following natural cycles for freeze-all strategy or to transfer supernumerary embryos from 2014-2021. Data were analyzed using SPSS Statistics software. We evaluated statistically significant differences using various tests including Fisher's test, chi-squared test and Wilcoxon's test.
Main results and the role of chance
A total of 2012 frozen-thawed cycles were included in the analysis; in 977 of them, blastocysts were transferred after a 2-4h post-thaw period and in 1035, blastocysts were transferred after a 20-22h post thaw culture period. The age of the women was comparable (35.4 ± 4.2 and 35.3 ± 4.1; p = 0.5, respectively in the short and long culture period). According to statistical analysis, no significant difference in pregnancy outcomes was found between the two groups. Live birth rate was respectively 40% and 42% ( p = 0.2) in the short and long post-thaw blastocyst culture period prior to transfer.
Limitations, reasons for caution
Our study was limited by the retrospective nature and was performed in a single fertility center. Moreover, only blastocysts vitrified on day 5 were evaluated and findings might not be generalized to day 6 and 7 blastocysts.
Wider implications of the findings
These findings might be useful in the context of the organization of the laboratory workflow. Indeed, the possibility to thaw blastocysts on the day before transfer may represent an advantage in order to avoid an overload of the laboratory procedures during very busy days.

Abstract
Study question
How many retracted papers are there in the medically assisted reproduction (MAR) literature and, more importantly, what are their particulars?
Summary answer
Article retraction within MAR literature is increasing and the most common reasons for retraction are errors in data and duplicate publications.
What is known already
Article retraction accounts for one of the most serious consequences of research misconduct. Articles may be subject to retraction whenever the findings are found to be unreliable, redundant, plagiarised or the authors are found to have performed unethical research or hidden

Abstract
Abstract
Study question
Is failure mode and effects analysis (FMEA) a useful and effective method of risk assessment in a gamete donor program?
Summary answer
The analysis of the potential failures, their causes and effects significantly improved the safety strategies previously adopted in our gamete donor program.
What is known already
At present, in Italy, the donation of fresh gametes is possible, but almost unmanageable due to the lack of donors and the refund to donors forbidden by law. As a result, many IVF Italian Centers established agreements with foreign gametes cryo-banks in order to meet the huge demand for donation treatments. The exchange of personal sensitive data and gametes between the sending and receiving centers represents a crucial aspect in a donor cycle. Each stage of this process, from gamete request to gamete thawing, is not error-free. FMEA represents a strategy to identify and mitigate potential failures before they occur.
Study design, size, duration
Fifty-eight oocyte and 4 sperm donation cycles were performed at our IVF facility from September 2019 to January 2021. Gametes came from a single Spanish cryo-bank. FMEA represents a proactive risk evaluation tool useful to identify real or potential failures and to develop actions to minimize risks. FMEA was conducted, in January 2021, by a team consisting of 2 gynaecologists, 3 embryologists and 2 quality managers and repeated 8 months later.
Participants/materials, setting, methods
Processes were analyzed to identify and score the potential failure modes using the risk priority number (RPN) scoring system. The calculation has been obtained by multiplying 3 factors: severity, occurrence and detectability scored from 1-5. After calculating the criticality of each failure mode, an action plan was prepared and then effectiveness of new process was monitored. Finally, FMEA was repeated and the improved RPN after the corrective actions was calculated.
Main results and the role of chance
In our gamete donation program, we mapped four phases: gamete request, donor-recipient matching, gamete delivery and gamete thawing. All the steps presented multiple failures and 11 different potential failure modes had been identified. Failure modes as the incorrect transcription of the recipient data, the acceptance of a donor proposal not well-matched with recipients and the receipt of gametes unsuitable for the couple correlate to high-risk scores with 30 RPN. These events may have severe consequences such as an incorrect matching between donor and recipient, and the subsequent birth of a child from a mismatched donor. Although gamete request, donor-recipient matching and receiving gametes phases are mainly characterized by document checking, the introduction of witnessing by another physician or embryologist, reduced the risk by 50%. Therefore, the introduction of double checking by a second operator represents an essential control measure to avoid errors.
Limitations, reasons for caution
This study is influenced by the general limitations of the FMEA approach, such as different personal experiences and skills of the participants since failures may be unrecognized, underestimated or overstated.
Wider implications of the findings
Performing a risk assessment in a donor program represents a valid strategy to mitigate risks of incorrect matching and loss of traceability. Since errors in data record and acceptance of donor proposal may cause important down streaming consequences, the double witnessing is strongly encouraged.

Abstract
Abstract
Study question
We aimed to verify whether endometriosis patients who succeeded in achieving a live birth through IVF were epigenetically younger than those who did not.
Summary answer
Applying peripheral blood epigenetic clock, endometriosis women who delivered a baby after assisted reproductive technology (ART) procedures were epigenetically younger than those who did not.
What is known already
The revolution of “epigenetic clocks”, based on DNA methylation, has ushered in a new era. Epigenetic clocks reflect the possible gap between chronological and biological age. They have recently gained attention also in the reproductive field, since epigenetic mechanisms have been suggested to influence fertility. Moreover, endometriosis progression has been linked to epigenetic factors and the genetic/epigenetic theory has been suggested as a unification theory for its pathogenesis.
Study design, size, duration
This is a secondary analysis of an observational cohort study, set at the Infertility Unit where we work. In the original study, we prospectively recruited women aged 37-39 years scheduled for an ART procedure between January 2017 and December 2018. For the present study, we considered only women with endometriosis and divided them into two groups: those who delivered and those who did not.
Participants/materials, setting, methods
Recruited patients did not suffer of relevant systemic diseases, had normal weight and serum FSH levels, and their male partners were not severely infertile. Before the beginning of the IVF cycle, blood samples were collected in EDTA-containing tubes and stored. After DNA extraction, epigenetic age was calculated considering the methylation pattern of 5 CpG sites as reported by Zbieć-Piekarska in 2018. The methylation pattern at these sites were compared between the two groups.
Main results and the role of chance
Thirty-eight women were enrolled. The cause of infertility was only endometriosis in 33 women or mixed with a concomitant mild male factor in 5 couples. Overall, 12 women (32% of our cohort) obtained a live birth. Women who had a live birth were characterized by higher antral follicular count compared to those who did not with a median value of 10 [6 – 14] and 13 [8-20] respectively (p < 0.02) and lower FSH (6.2 UI/L [5.8-7.5] and 8.3 [6.9-9.6], p 0.01 respectively). After ART, they obtained a higher number of suitable oocytes and cleavage stage embryos. Statistically significant difference emerged for epigenetic age (p < 0.05). Specifically, the median value and interquartile range was 34.5 [32.3 – 37.5] and 36.0 [35.0 – 38.3] for endometriosis women who did and did not have a live birth. The statistically significant epigenetic gap persisted even after adjusting for serum anti-mullerian hormone (AMH).
Limitations, reasons for caution
This is a secondary analysis of a cohort study designed for infertility in general, the sample size was limited, and we included only women aged 37-39 years: confirmation in larger studies with broader selection criteria and specifically designed for endometriosis is warranted. Moreover, other epigenetic clocks could have been considered.
Wider implications of the findings
Our study highlighted the relevance of epigenetics in endometriosis-related infertility. Epigenetic clocks could predict IVF success in affected women. Moreover, a deeper comprehension of these epigenetic mechanisms could lead to interventions aimed at reversing their effects, including modification of such lifestyle factors or hormonal medical treatments.

Abstract
Study question
Does endometriosis affect the expression of the aromatase gene CYP19A1 in the cumulus oophorous (COCs) and mural lutein-granulosa cells (GCs) influencing ART procedures?
Summary answer
Endometriosis does not impair CYP19A1 gene expression. However, the correlation between the aromatase expression and the number of oocytes retrieved is lost in endometriosis patients.
What is known already
Endometriosis-related infertility could be associated with a dysregulation of oocytes development. Indeed, endometriosis seems to have a negative effect on the intrafollicular environment, hindering oocyte maturation. A dysregulated synthesis of steroid hormones by GCs in the ovaries of affected women may be at the basis of an inadequate folliculogenesis. In line, some studies have investigated the expression levels of aromatase p450 ( CYP19A1 ) -the key enzyme involved in 17β-estradiol (E2) synthesis - in GCs and COCs collected from endometriosis women, reporting controversial results.
Study design, size, duration
In order to identify novel prognostic factors of ART outcomes in affected women, we set the evaluation of CYP19A1 expression in GCs samples isolated from endometriosis patients undergoing ART in comparison to control women. In a subgroup of patients, COCs were also collected. CYP19A1, StAR and 3βHSD gene expression was evaluated in both cell types. Finally, we evaluated the association between the expression of the analyzed genes and E2 levels with the clinical ART outcomes
Participants/materials, setting, methods
GCs were isolated from follicular fluids(FF) of n = 68 women with stage III-IV endometriosis and of n = 69 control patients. CYP19A1 gene expression was quantified by qPCR. 17β-estradiol levels in FF were assessed using an ELISA kit. In addition to CYP19A1 gene expression, mRNA levels of StAR and 3βHSD both in GCs and COCs (n = 20 endometriosis;n=21 controls) were evaluated in both cell types using qPCR. Differences between the two patients’ groups were estimated using linear regression models.
Main results and the role of chance
qPCR results showed no differences in mRNA expression of CYP19A1, StAR and 3βHSD in both GCs and COCs between the two groups of ART patients. These results were supported by the presence of the same concentration of E2 in the FF of controls (median: 877.7 ng/mL) and endometriosis patients (median: 878.3 ng/mL) (p-value=0.87). Linear regression model including as input variables gene expression values and ART outcomes showed that the blastulation rate was the only ART outcome associated with the expression levels of CYP19A1 (p-value=0.043, 95% CI: 0.001-0.061). In particular, a decrease of aromatase levels was associated with an increase in blastulation rate. After stratification of the population based on the presence of the disease, it emerged that, in the control group, the CYP19A1 expression correlated with the number of oocytes retrieved [β:-1.214;95%CI: -2.085 - (-0.343); p-value=0.007], while in the group of patients with endometriosis this association was no more present [β:-0.003;95%CI:-0.468 - 0.461; p-value=0.988)]. These results do not support data from the literature indicating that aromatase expression is reduced in GCs of affected women, but they highlight a potential disease-related mechanism affecting the ovulation process in these women
Limitations, reasons for caution
These findings need to be validated in a different cohort of samples. An RNA-seq approach is needed in order to validate our results and to obtain the overall transcriptome profiles of GCs and COCs in endometriosis patients.
Wider implications of the findings
Our data do not confirm previous evidence supporting a reduced expression/activity of aromatase in GCs in endometriosis. However, they suggest that aromatase may have a complex and sophisticated regulation of its expression in this cell type, which is not maintained in presence of endometriosis.

Abstract
Study question
Do viable pregnancies after transfer of mosaic blastocysts present different perinatal outcomes as compared to those deriving from transfer of euploid blastocysts?
Summary answer
Pregnancies from transfer of mosaic vs. euploid blastocysts showed an increased rate of fetal structural malformations and postpartum haemorrhages (PPH).
What is known already
The incidence of mosaicisms in the trophoectoderm is a relatively frequent event and most true embryo mosaicisms result in spontaneous intrauterine demise. The confirmation of the mosaic aneuploidy in the fetus is related to the type and grade of the aneuploidy with higher risk for chromosomes 13, 14, 15, 16, 18 and 21 and X monosomy. On the other hand, selected mosaic blastocysts have been transferred with subsequent birth of healthy neonates. However, the risk of abnormal obstetric outcomes after transfer of mosaic embryos remains to be completely elucidated.
Study design, size, duration
Explorative cohort study between 2016 and 2021 including consecutive viable ART pregnancies developing from transfer of mosaic blastocysts (n = 39 cases). Transfer of available mosaic embryos was considered for patients with a poor response to ovarian stimulation or recurrent implantation failures and no available euploid blastocysts, after genetic counselling. Cases were matched for maternal age, parity and body mass index to women with viable pregnancies after transfer of euploid blastocysts (n = 39, controls) and followed-up until delivery.
Participants/materials, setting, methods
All patients recruited at San Raffaele, Scientific Institute of Milan, underwent a prenatal genetic testing by trophoectoderm biopsy and next-generation sequencing analysis. Patients with a viable fetus at 12 weeks gestation were included and underwent detailed ultrasound assessment at 12, 20 and 32 weeks including fetal biometry and anatomical survey. Frequency of adverse pregnancy and perinatal outcomes including maternal, fetal and delivery complications were compared between patients who received a mosaic versus a euploid blastocyst.
Main results and the role of chance
No difference in indications to preimplantation diagnosis was found between cases and controls. In the group who transferred mosaic embryos, median rate of mosaicisms was 35% (IQR 30%-40%) and they were characterized by heterogeneous anomalies including complex aneuploidies (n = 12), autosomal monosomies (n = 13), trisomies (n = 8) and duplications/deletions (n = 6). Invasive testing was performed in 62.0% of mosaics (5 chorion villous samplings; 19 amniocenteses; 2 anomalies: confined placental mosaicism trisomy 15 after transfer of mosaic monosomy 6 and fetal microduplication 6p after transfer of mosaic deletion 10p) vs 2.5% of controls (p < 0.001). Structural malformations were observed in 6 neonates in the study group (tanatophoric skeletal dysplasia, complex central nervous system anomaly, congenital diaphragmatic hernia, cerebral arteriovenous fistulae, pyeloureteral junction stenosis, diffuse haemangiomatosis) compared to 1 in controls (pulmonary stenosis) (p = 0.04). One neonate per group was followed-up for future surgery. PPH rate was significantly higher in cases vs controls (15 vs 7; p = 0.04). Neonatal survival at hospital discharge was not different in the two groups (p = 0.30). No significant differences were recorded in rates of preterm birth, small or large for gestational age, fetal growth restriction, miscarriage, preeclampsia and median birthweight centile or gestational age at birth.
Limitations, reasons for caution
Data from our exploratory study should be interpreted cautiously given the limited sample size which makes it challenging to infer a causal relationship between the association found and transfer of mosaic blastocysts.
Wider implications of the findings
The higher rates of structural malformations and PPH in ART pregnancies after transfer of mosaic embryos strongly suggest the need for strict monitoring of these patients. First and second trimester ultrasound screening for structural defects, and preventive measures to minimize bleeding at delivery should be implemented.

Abstract
Abstract
Study question
The present study was designed to better elucidate if endometriosis may affect follicologenesis and embryo development within a cycle of ovarian hyperstimulation for IVF (In Vitro Fertilization).
Summary answer
Endometriosis women showed fewer oocytes retrieved and a higher rate of unexpected poor response albeit number of patients without good quality embryos was similar.
What is known already
The pathogenetic mechanisms explaining the association between endometriosis and infertility are not fully explained. Pelvic adhesions and inflammation may play a role but other detrimental effects are presumably involved. They include reduced ovarian reserve, altered oocyte competence, impaired endometrial receptivity and association with other conditions affecting fertility such as adenomyosis. To note, even if in vitro fertilization is expected to overcome the pelvic detrimental milieu, the success rate of the procedure is lower in women with endometriosis.
Study design, size, duration
We designed a clinical retrospective study in order to analyse the impact of the disease on ovarian hyperstimulation and embryo development. Women were selected among those undergoing IVF cycles between January 2014 and December 2020. The primary outcome was the number of women without top quality embryos. Secondary outcomes included the rate of unexpected poor response (retrieval of ≤ 3 oocytes), cumulative clinical pregnancy rate and cumulative birth rate.
Participants/materials, setting, methods
Our study was performed at the Infertility Unit of the Fondazione IRCSS Ca’ Granda Ospedale Maggiore Policlinico of Milan. We included 496 subjects with a good ovarian reserve as demonstrated by serum Anti-mullerian hormone (AMH) > 1,1 ng/ml. Two hundreds and forty-eight women with endometriosis were identified and matched with two hundreds and forty-eight women without the disease according to age, pharmacological regimen, study period and AMH levels.
Main results and the role of chance
The number of women without good quality embryos did not differ between exposed and unexposed subjects (16% vs 16%, p = 1.00). The adjusted OR was 0.85 (95%CI: 0.51-1.44, p = 0.56). The clinical pregnancy rate and the live birth rate were also similar. We observed a lower number of oocytes retrieved and a higher rate of unexpected poor response (23% vs 13%, p = 0.005) in women with endometriosis. At subgroup analysis, the higher rate of unexpected poor responders persisted only in previously operated women (27% vs 13%, p = 0.02).
Limitations, reasons for caution
The evaluation of embryo quality was only based on morphological criteria. The histological diagnosis of endometriosis was lacking in unoperated women (128 subjects). Finally, our conclusions concern ovarian hyperstimulation and may not be extrapolated to natural reproductive processes.
Wider implications of the findings
Despite being generally reassuring, our findings do not completely exclude some mild negative effects on folliculogenesis. Effects demonstrated could be due to anatomical distortions of the pelvis causing an inefficient response of the ovarian parenchyma to hyperstimulation. We cannot exclude that the post-surgical healing process may alter local vascular supply.

Abstract
Abstract
Study question
Can the UF-EVs transcriptome provide markers of implantation in women diagnosed with recurrent implantation failure (RIF)?
Summary answer
Enrichment in IL-10 and IL-17 pathway transcripts in UF-EVs of women with RIF might identify those at risk for negative outcome after euploid blastocyst transfer.
What is known already
Our group has recently found that transcriptomic changes occur in UF-EVs during the window of implantation and closely resemble those occurring in the endometrial tissue. Patients affected by RIF represent a debated and heterogeneous population of patients who currently undergo several investigations, empirical therapies and embryo transfer attempts, with inconclusive results. We investigated whether UF-EVs can provide markers to define subgroups of patients within the RIF population, to predict outcomes and tailor interventions.
Study design, size, duration
We herein present the first sub-analysis of our previous larger observational study on the human UF-EVs transcriptome (Giacomini et al., 2021). RIF was defined by > 3 failed embryo transfers (ETs) with high quality embryos and patients affected by RIF and undergoing their first PGT-A cycle were enrolled (n = 19). Fertile women undergoing PGT-A+PGT-M for monogenic diseases and achieving successful implantation were used as controls (n = 29). PGT-A was performed by Next Generation Sequencing.
Participants/materials, setting, methods
RNA-Seq was performed on UF-EVs collected on day LH + 7 of the cycle preceding that of the blastocyst transfer. Differential Gene Expression (DGE) analysis was performed between RIF patients failing implantation (Group A) versus RIF patients achieving implantation (Group B) and between Group A and fertile controls achieving implantation (Group C). Pre-ranked gene set enrichment (GSEA) with WebGestalt was used for pathway enrichment analysis, with Normalized Enrichment Score (NES) indicating the strength of the enrichment.
Main results and the role of chance
RIF patients had a mean (± SD) age of 36.6 (± 3.4) and 5.1 ± 2.1 (mean ± SD) previous failed ETs. DGE comparisons between UF-EVs of RIF women who failed implantation (n = 10) showed 135 up- and 32 down-regulated genes compared to Group B, and 258 up- and 44 down-regulated genes compared to Group C, with 63 genes showing consistent significantly different ‘expression’ values in both comparisons. UF-EVs of Group A were enriched in transcripts belonging to the IL-17 pathway compared to both groups (Group A vs B, NES=2.2044, FDR <0.0001; Group A vs C, NES=2.3584, FDR <0.0001).Also transcripts belonging to the IL-10 pathway were enriched compared to both groups (Group A vs B NES=2.2741, FDR = 0.002; Group A vs C NES=2.2047, FDR < 0.0001). Among genes enriched in both DGE comparisons, C-X-C motif chemokine ligand (CXCL)1, CXCL2, CXCL8, and prostaglandin-endoperoxide synthase 2 (PTGS2) belonged to both the IL-10 and IL-17 pathway. On multivariate analysis controlling for relevant confounders (i.e. number of previous failed ETs), expression levels of CXCL8 emerged as a significant negative predictor of implantation (OR 0.675, 95%CI 0.493-0.925, p = 0.01).
Limitations, reasons for caution
As the main limitation of our study, we collected UFs in the cycle immediately preceding (and not corresponding to) the euploid ET. This approach was considered the most appropriate in relation to the current paucity of data regarding the safety of UF aspiration in the same cycle of an ET.
Wider implications of the findings
UF-EVs represent a source of transcriptomic markers related to the endometrial immune profile in RIF patients. Enrichment in the IL-17 and IL-10 pathways in this population could define the subgroup who is at risk for implantation failure even after euploid ET and who could potentially benefit from tailored immunotherapies.

Abstract
Purpose To evaluate obstetric outcome in women with endometriosis who conceive naturally and receive standard obstetric care in Italy. Methods Cases were consecutive women with endometriosis managed in eleven Italian referral centers. Controls were women in whom endometriosis was excluded. All women filled in a questionnaire addressing previous natural pregnancies. Marginal logistic regression models were fitted to evaluate the impact of endometriosis on obstetric outcome. A post hoc analysis was performed within the endometriosis group comparing women with severe adenomyosis versus women with absent or mild adenomyosis. Results Three hundred and fifty-five pregnancies in endometriosis group and 741 pregnancies in control group were included. Women with endometriosis had a higher risk of preterm delivery < 34 weeks (6.4% vs 2.8%, OR 2.42, 95% CI 1.22–4.82), preterm delivery < 37 weeks (17.8% vs 9.7%, OR 1.98, 95% CI 1.23–3.19), and neonatal admission to Intensive Care Unit (14.1% vs 7.0%, OR 2.04, 95% CI 1.23–3.36). At post hoc analysis, women with endometriosis and severe adenomyosis had an increased risk of placenta previa (23.1% vs 1.8%, OR 16.68, 95% CI 3.49–79.71), cesarean delivery (84.6% vs 38.9%, OR 8.03, 95% CI 1.69–38.25) and preterm delivery < 34 weeks (23.1% vs 5.7%, OR 5.52, 95% CI 1.38–22.09). Conclusion Women with endometriosis who conceive naturally have increased risk of preterm delivery and neonatal admission to intensive care unit. When severe adenomyosis is coexistent with endometriosis, women may be at increased risk of placenta previa and cesarean delivery. Trial registration Clinical trial registration number: NCT03354793.

Abstract
Abstract
Study question
Could EVs secreted by aneuploid embryos a) serve for development of RNA biomarkers for PGT-A and b) elicit a relevant transcriptomic response in decidualised ESCs?
Summary answer
Aneuploid embryo EVs a) contain PPM1J, LINC00561, ANKRD34C and TMED10 in differential abundance from euploid EVs and b) induce up-regulation of MUC1 in decidualised ESCs.
What is known already
Embryo aneuploidy accounts for approximately 50% of all recurrent implantation failures in women >35 years old. PGT-A identifies euploid embryos to increase implantation probability but the technology is controversial as it requires an invasive embryo biopsy with an elusive long-term biosafety. The development of non-invasive methods to screen out aneuploid embryos is paramount. It is also critical to decode the embryo-endometrial dialog underlying implantation failure. We have previously reported that IVF embryos secrete EVs that can be internalised by ESCs, conceptualising that successful implantation to the endometrium is facilitated by EVs, which may additionally serve as biomarkers of ploidy status.
Study design, size, duration
Embryos destined for biopsy on days 5-7 for PGT-A were grown under standard conditions. Spent media (30μl) were collected from euploid (n = 175) and aneuploid embryos (n = 145) at both cleavage (days 1-3) and blastocyst (days 3-5) stage. Media samples from n = 35 cleavage embryos were pooled in order to obtain five euploid and four aneuploidy pools. Blastocyst media were pooled to create one euploid and one aneuploid pool. ESCs were obtained from five women undergoing diagnostic laparoscopy.
Participants/materials, setting, methods
The study was realised at a research hospital. EVs were isolated from euploid and aneuploid Day3 pools with differential ultracentrifugation and EV-RNA sequencing was performed following the SMARTer Stranded Total RNA-Seq approach. ESCs were decidualised (E2:10nM, P4:1uM, cAMP:0.5 mM twice every 48 hours) and treated for 24 hours with 50 ng/ml euploid or aneuploid EVs extracted from blastocyst media. RNA sequencing was performed on ESCs following the Truseq RNAseq protocol.
Main results and the role of chance

Abstract
Study question
Could EVs secreted by aneuploid embryos a) serve for development of RNA biomarkers for PGT-A and b) elicit a relevant transcriptomic response in decidualised ESCs?
Summary answer
Aneuploid embryo EVs a) contain PPM1J, LINC00561, ANKRD34C and TMED10 in differential abundance from euploid EVs and b) induce up-regulation of MUC1 in decidualised ESCs.
What is known already
Embryo aneuploidy accounts for approximately 50% of all recurrent implantation failures in women >35 years old. PGT-A identifies euploid embryos to increase implantation probability but the technology is controversial as it requires an invasive embryo biopsy with an elusive long-term biosafety. The development of non-invasive methods to screen out aneuploid embryos is paramount. It is also critical to decode the embryo-endometrial dialog underlying implantation failure. We have previously reported that IVF embryos secrete EVs that can be internalised by ESCs, conceptualising that successful implantation to the endometrium is facilitated by EVs, which may additionally serve as biomarkers of ploidy status.
Study design, size, duration
Embryos destined for biopsy on days 5–7 for PGT-A were grown under standard conditions. Spent media (30μl) were collected from euploid (n = 175) and aneuploid embryos (n = 145) at both cleavage (days 1–3) and blastocyst (days 3–5) stage. Media samples from n = 35 cleavage embryos were pooled in order to obtain five euploid and four aneuploidy pools. Blastocyst media were pooled to create one euploid and one aneuploid pool. ESCs were obtained from five women undergoing diagnostic laparoscopy.
Participants/materials, setting, methods
The study was realised at a research hospital. EVs were isolated from euploid and aneuploid Day3 pools with differential ultracentrifugation and EV-RNA sequencing was performed following the SMARTer Stranded Total RNA-Seq approach. ESCs were decidualised (E2:10nM, P4:1uM, cAMP:0.5 mM twice every 48 hours) and treated for 24 hours with 50 ng/ml euploid or aneuploid EVs extracted from blastocyst media. RNA sequencing was performed on ESCs following the Truseq RNAseq protocol.
Main results and the role of chance
Aneuploid cleavage stage embryos (n = 4) secreted EVs that were less abundant in RNA fragments originating from the genes PPM1J (log2fc=–5.13, p = 0.011), LINC00561 (log2fc=–7.87, p = 0.010) and ANKRD34C (log2fc=–7.30, p = 0.017) and more abundant in TMED10 (log2fc=1.63 p = 0.025) compared to EVs (n = 5) from euploid embryos. Decidualisation per se induced downregulation of MUC1 (log2FC=–0.54, p = 0.0028) in ESCs as prerequisite for the establishment of receptive endometrium. The expression of MUC1 transcript in decidualised ESCs was significantly increased following treatment with aneuploid compared to euploid embryo-secreted EVs (log2FC=0.85, p = 0.0201).
Limitations, reasons for caution
The findings of the study may require validation utilising a second cohort of EVs samples.
Wider implications of the findings: This discovery that the RNA cargo of EVs secreted from aneuploid cleavage stage embryos is diverse from that of euploid embryos potentiates the development of non-invasive methodology for PGT-A. The upregulation of MUC1 in decidualised ESCs following aneuploid embryo EV treatment proposes a new mechanism underlying implantation failure.

Abstract
STUDY QUESTION Are uterine fluid-derived extracellular vesicles (UF-EVs) a 'liquid biopsy' reservoir of biomarkers for real-time monitoring of endometrial status? SUMMARY ANSWER The transcriptomic cargo of UF-EVs reflects the RNA profile of the endometrial tissue as well as changes between the non-receptive and the receptive phase, possibly supporting its use for a novel endometrial receptivity test. WHAT IS KNOWN ALREADY EVs have been previously isolated from uterine fluid, where they likely contribute to the embryo-endometrium crosstalk during implantation. Based on a meta-analysis of studies on endometrial tissue implantation-associated genes and the human exosomes database, 28 of the 57 transcripts considered as receptivity markers refer to proteins present in human exosomes. However, the specific transcriptomic content of receptive phase UF-EVs has yet to be defined. STUDY DESIGN, SIZE, DURATION Two experimental series were set up. First, we simultaneously sequenced RNA species derived from paired UF-EVs and endometrial tissue samples collected from physiologically cycling women. Second, we analyzed RNA species of UF-EVs collected during the non-receptive (LH + 2) and receptive (LH + 7) phase of proven fertile women and from the receptive (LH + 7) phase of a population of women undergoing ART and transfer of euploid blastocysts. PARTICIPANTS/MATERIALS, SETTING, METHODS For paired UF-endometrial tissue sampling, endometrial tissue biopsies were obtained with the use of a Pipelle immediately after UF collection performed by lavage of the endometrial cavity. Overall, n = 87 UF samples were collected and fresh-processed for EV isolation and total RNA extraction, while western blotting was used to confirm the expression of EV protein markers of the isolated vesicles. Physical characterization of UF-EVs was performed by Nanoparticle Tracking Analysis. To define the transcriptomic cargo of UF-EV samples, RNA-seq libraries were successfully prepared from n = 83 UF-EVs samples and analyzed by RNA-seq analysis. Differential gene expression (DGE) analysis was used to compare RNA-seq results between different groups of samples. Functional enrichment analysis was performed by gene set enrichment analysis with g:Profiler. Pre-ranked gene set enrichment analysis (GSEA) with WebGestalt was used to compare RNA-seq results with the gene-set evaluated in a commercially available endometrial receptivity array. MAIN RESULTS AND THE ROLE OF CHANCE A highly significant correlation was found between transcriptional profiles of endometrial biopsies and pairwise UF-EV samples (Pearson's r = 0.70 P < 0.0001; Spearman's ρ = 0.65 P < 0.0001). In UF-EVs from fertile controls, 942 gene transcripts were more abundant and 1305 transcripts less abundant in the LH + 7 receptive versus the LH + 2 non-receptive phase. GSEA performed to evaluate concordance in transcriptional profile between the n = 238 genes included in the commercially available endometrial receptivity array and the LH + 7 versus LH + 2 UF-EV comparison demonstrated an extremely significant and consistent enrichment, with a normalized enrichment score (NES)=9.38 (P < 0.001) for transcripts up-regulated in LH + 7 in the commercial array and enriched in LH + 7 UF-EVs, and a NES = -5.40 (P < 0.001) for transcripts down-regulated in LH + 7 in the commercial array and depleted in LH + 7 UF-EVs. When analyzing LH + 7 UF-EVs of patients with successful versus failed implantation after transfer of one euploid blastocyst in the following cycle, we found 97 genes whose transcript levels were increased and 64 genes whose transcript levels were decreased in the group of women who achieved a pregnancy. GSEA performed to evaluate concordance in transcriptional profile between the commercially available endometrial receptivity array genes and the comparison of LH + 7 UF-EVs of women with successful versus failed implantation, demonstrated a significant enrichment with a NES = 2.14 (P = 0.001) for transcripts up-regulated in the commercial array in the receptive phase and enriched in UF-EVs of women who conceived, and a not significant NES = -1.18 (P = 0.3) for transcripts down-regulated in the commercial array and depleted in UF-EVs. In terms of physical features, UF-EVs showed a homogeneity among the different groups analyzed except for a slight but significant difference in EV size, being smaller in women with a successful implantation compared to patients who failed to conceive after euploid blastocyst transfer (mean diameter ± SD 205.5± 22.97 nm vs 221.5 ± 20.57 nm, respectively, P = 0.014). LARGE SCALE DATA Transcriptomic data were deposited in NCBI Gene Expression Omnibus (GEO) and can be retrieved using GEO series accession number: GSE158958. LIMITATIONS, REASONS FOR CAUTION Separation of RNA species associated with EV membranes might have been incomplete, and membrane-bound RNA species-rather than the internal RNA content of EVs-might have contributed to our RNA-seq results. Also, we cannot definitely distinguish the relative contribution of exosomes, microvesicles and apoptotic bodies to our findings. When considering patients undergoing ART, we did not collect UFs in the same cycle of the euploid embryo transfer but in the one immediately preceding. We considered this approach as the most appropriate in relation to the novel, explorative nature of our study. Based on our results, a validation of UF-EV RNA-seq analyses in the same cycle in which embryo transfer is performed could be hypothesized. WIDER IMPLICATIONS OF THE FINDINGS On the largest sample size of human EVs ever analyzed with RNA-seq, this study establishes a gene signature to use for less-invasive endometrial receptivity tests. This report is indeed the first to show that the transcriptome of UF-EVs correlates with the endometrial tissue transcriptome, that RNA signatures in UF-EVs change with endometrial status, and that UF-EVs could serve as a reservoir for potential less-invasive collection of receptivity markers. This article thus represents a step forward in the design of less-invasive approaches for real-time monitoring of endometrial status, necessary for advancing the field of reproductive medicine. STUDY FUNDING/COMPETING INTEREST(S) The study was funded by a competitive grant from European Society of Human Reproduction and Embryology (ESHRE Research Grant 2016-1).

Abstract
STUDY QUESTION Is late follicular elevated progesterone (LFEP) in the fresh cycle hindering cumulative live birth rates (CLBRs) when a freeze only strategy is applied? SUMMARY ANSWER LFEP in the fresh cycle does not affect the CLBR of the frozen transfers in a freeze only approach, nor the embryo freezing rate. WHAT IS KNOWN ALREADY Ovarian stimulation promotes the production of progesterone (P) which has been demonstrated to have a deleterious effect on IVF outcomes. While there is robust evidence that this elevation produces impaired endometrial receptivity, the impact on embryo quality remains a matter of debate. In particular, previous studies have shown that LFEP is associated with a hindered CLBR. However, most clinical insight on the effect of progesterone on embryo quality in terms of CLBRs have focused on embryo transfers performed after the fresh transfer, thus excluding the first embryo of the cohort. To be really informative on the possible detrimental effects of LFEP, evidence should be derived from freeze-all cycles where no fresh embryo transfer is performed in the presence of progesterone elevation, and the entire cohort of embryos is cryopreserved. STUDY DESIGN, SIZE, DURATION This was a matched case-control, multicentre (three centres), retrospective analysis including all GnRH antagonist ICSI cycles in which a freeze all (FA) policy of embryos on day 3/5/6 of embryonic development was applied between 2012 and 2018. A total of 942 patients (471 cases with elevated P and 471 matched controls with normal P values) were included in the analysis. Each patient was included only once. PARTICIPANTS/MATERIALS, SETTING, METHODS The sample was divided according to the following P levels on the day of ovulation triggering: <1.50 ng/ml and ≥1.50 ng/ml. The matching of the controls was performed according to age (±1 year) and number of oocytes retrieved (±10%). The main outcome was CLBR defined as a live-born delivery after 24 weeks of gestation. MAIN RESULTS AND THE ROLE OF CHANCE The baseline characteristics of the two groups were similar. Estradiol levels on the day of trigger were significantly higher in the elevated P group. There was no significant difference in terms of fertilisation rate between the two groups. The elevated P group had significantly more cleavage stage frozen embryos compared to the normal P group while the total number of cryopreserved blastocyst stage embryos was the same. The CLBR did not differ between the two study groups (29.3% and 28.2% in the normal versus LFEP respectively, P = 0.773), also following confounder adjustment using multivariable GEE regression analysis (accounting for age at oocyte retrieval, total dose of FSH, progesterone levels on the day of ovulation trigger, day of freezing, at least one top-quality embryo transferred and number of previous IVF cycles, as the independent variables). LIMITATIONS, REASONS FOR CAUTION This is a multicentre observational study based on a retrospective data analysis. Better extrapolation of the results could be validated by performing a prospective analysis. WIDER IMPLICATIONS OF THE FINDINGS This is the first study demonstrating that LFEP in the fresh cycle does not hinder CLBR of the subsequent frozen cycles in a FA approach. Thus, a FA strategy circumvents the issue of elevated P in the late follicular phase. STUDY FUNDING/COMPETING INTEREST(S) No funding was received for this study.

Abstract
SETTING: QuantiFERON TB assay (QFT) is used to screen tuberculosis (TB) infection, but it cannot distinguish active TB from latent TB infection (LTBI).OBJECTIVE: To evaluate the quantitative expression of the high-affinity FCgamma receptor I (CD64) on neutrophils (NE) and monocytes (MO) in peripheral blood using flow cytometry, measured in antibody binding capacity (ABC) units as a predictive biomarker of TB.DESIGN: Fifty-two patients were enrolled (45 QFT-positive and 7 QFT-indeterminate). Cultures and molecular analyses were performed.RESULTS: Of the 45 QFT-positive patients, 29 were culture-positive (active TB) and 16 were negative (LTBI). The median NE CD64 ABC and MO CD64 ABC expression was significantly higher (P < 0.001) in culture-positive patients. The NE CD64 and MO CD64 area under the receiver operating characteristic curve values were respectively 0.948 (95%CI 0.838-0.992) and 0.989 (0.901-1.000). By setting the cut-off NE CD64 value at >2400 ABC or MO CD64 value >25 800 the assay sensitivity increased to 95.5% with 100% specificity and 100% positive predictive value. In the QFT-indeterminate group, five culture-positive cases had NE CD64 >2400 ABC or MO CD64 value >25 800; two culture-negative cases had lower values.CONCLUSION: The CD64 quantitative expression on peripheral blood cells may be used as a predictive biomarker for active TB.

Abstract
Introduction: Systemic Autoimmune Diseases (SADs) include systemic lupus erythematosus, antiphospholipid antibody syndrome, rheumatoid arthritis, systemic sclerosis, Sjogren's syndrome, mixed connective tissue disease, idiopathic inflammatory myopathies and vasculitis. SADs often occur in women of childbearing age and can affect fertility. Both infertility treatments and fertility preservation techniques are thus often indicated. Areas covered: The literature regarding the safety of fertility-related drugs for both fertility preservation and infertility treatment in patients affected by SADs was reviewed. Based on current knowledge, all the options for fertility preservation should be contemplated in patients with SADs who are at risk for fertility loss, including GnRH analogue administration, oocyte/embryo vitrification and ovarian tissue cryopreservation. Similarly, if pregnancy is not contraindicated in a patient with a SAD, neither should be any fertility treatment. Expert opinion: Women with SADs should postpone conception until a stable disease has been achieved for at least 6 months. When infertility treatments are needed, women with antiphospholipid antibodies should receive concomitant anticoagulation. If in vitro fertilization/intra-cytoplasmic sperm injection and embryo transfer is required, ovarian hyperstimulation and the inherent risk of thrombosis should be eliminated by GnRH-agonist trigger and cycle segmentation. Counselling about adherence to anti-rheumatic therapy to prevent disease exacerbations is also critical.

Abstract
Extracellular vesicle (EV) exchange is emerging as a novel method of communication at the maternal-fetal interface. The presence of the EVs has been demonstrated in the preimplantation embryo culture medium from different species, such as bovines, porcines and humans. Preimplantation embryo-derived EVs have been shown to carry molecules potentially able to modulate the local endometrial immune system. The non-classical major histocompatibility complex (MHC) class I molecule human leucocyte antigen (HLA)-G, the immunomodulatory molecule progesterone-induced blocking factor and some regulatory miRNAs species are contained in embryo-derived EV cargo. The implanted syncytiotrophoblasts are also well known to secrete EVs, with microvesicles exerting a mainly proinflammatory effect while exosomes in general mediate local immunotolerance. This review focuses on the current knowledge on the potential role of EVs released by the embryo in the first weeks of pregnancy on the maternal immune cells. Collectively, the data warrant further exploration of the dialogue between the mother and the embryo via EVs.

Abstract
The incidence of endometriosis in middle-aged women is not minimal compared to that in the reproductive age group. The treatment of affected women after childbearing age to the natural transition toward menopause has received considerably poor attention. Disease management is problematic for these women due to increased contraindications regarding hormonal treatment and the possibility for malignant transformation, considering the increased cancer risk in patients with a long-standing history of the disease. This state-of-the-art review aims for the first time to assess the benefits of the available therapies to help guide treatment decisions for the care of endometriosis in women approaching menopause. Progestins are proven effective in reducing pain and should be preferred in these women. According to the international guidelines that lack precise recommendations, hysterectomy with bilateral salpingo-oophorectomy should be the definitive therapy in women who have completed their reproductive arc, if medical therapy has failed. Strict surveillance or surgery with removal of affected gonads should be considered in cases of long-standing or recurrent endometriomas, especially in the presence of modifications of ultrasonographic cyst patterns. Although rare, malignant transformation of various tissues in endometriosis patients has been described, and management is herein discussed.

Abstract
Background An increased incidence of imprint-associated disorders has been reported in babies born from assisted reproductive technology (ART). However, previous studies supporting an association between ART and an altered DNA methylation status of the conceived babies have been often conducted on a limited number of methylation sites and without correction for critical potential confounders. Moreover, all the previous studies focused on the identification of methylation changes shared among subjects while an evaluation of stochastic differences has never been conducted. This study aims to evaluate the effect of ART and other common behavioral or environmental factors associated with pregnancy on stochastic epigenetic variability using a multivariate approach. Results DNA methylation levels of cord blood from 23 in vitro and 41 naturally conceived children were analyzed using the Infinium HumanMethylation450 BeadChips. After multiple testing correction, no statistically significant difference emerged in the number of cord blood stochastic epigenetic variations or in the methylation levels between in vitro- and in vivo-conceived babies. Conversely, four multiple factor analysis dimensions summarizing common phenotypic, behavioral, or environmental factors (cord blood cell composition, pre or post conception supplementation of folates, birth percentiles, gestational age, cesarean section, pre-gestational mother’s weight, parents’ BMI and obesity status, presence of adverse pregnancy outcomes, mother’s smoking status, and season of birth) were significantly associated with stochastic epigenetic variability. The stochastic epigenetic variation analysis allowed the identification of a rare imprinting defect in the locus GNAS in one of the babies belonging to the control population, which would not have emerged using a classical case-control association analysis. Conclusions We confirmed the effect of several common behavioral or environmental factors on the epigenome of newborns and described for the first time an epigenetic effect related to season of birth. Children born after ART did not appear to have an increased risk of genome-wide changes in DNA methylation either at specific loci or randomly scattered throughout the genome. The inability to identify differences between cases and controls suggests that the number of stochastic epigenetic variations potentially induced by ART was not greater than that naturally produced in response to maternal behavior or other common environmental factors.

Abstract
To evaluate presumptive differences in osseointegration at implants supporting crowns that are physiologically loaded either immediately or 3 months after installation. All premolars and first molars were extracted bilaterally in six dogs. After 3 months of healing, three implants were installed on the premolar region and two in the molar region in one side of the mandible. Likewise, after another 3 months, five implants were installed in the contralateral side, and impressions were taken bilaterally. Within 48 hours, two single crowns were screwed bilaterally onto two implants in the premolar region, and two splinted crowns reproducing the shape of the first molar were screwed bilaterally onto the implants in the molar region. The mesial implants were used as no-loaded controls. Sacrifices were performed after 3 months, and histological analyses were performed. At the premolar sites, mineralised bone-to-implant contact (MBIC%) was 78.0 ± 4.0% and 70.9 ± 7.9% at the delayed and immediately loaded sites, respectively. This difference was statistically significant. At the control implants, MBIC% was 61.4 ± 14.7% and 63.1 ± 13.1% at the delayed and the immediately loaded sites, respectively. At the molar sites, MBIC% was 79.2 ± 10.9% and 61.1 ± 10.3% at the delayed and immediately loaded sites, respectively. Applying a delayed loading to fixed dental prostheses supported by single or two splinted implants yielded higher proportions of bone-to-implant contact (osseointegration) compared to immediately loaded implants. Moreover, both types of loading protocols yielded a higher rate of osseointegration compared to unloaded implant sites after 3 months following implant installation.

Abstract
The hormone resistance of prostate cancer has been proved to depend at least in part on enhanced neuroendocrine activity and the resultant increase in blood concentrations of chromogranin A. Other experimental observations have suggested the involvement of prolactin (PRL), which appears to be a potential growth factor for prostate cancer. Abnormally high levels of PRL have been detected in metastatic prostate cancer, but the clinical significance of this finding has still to be clarified. In an attempt to explain the prognostic significance of serum PRL levels in prostate cancer, in this preliminary study we have analyzed the PRL levels in a group of metastatic prostate cancer patients with hormone-dependent or hormone-resistant cancer. The study included 50 patients with metastatic prostate cancer, 15 of whom had hormone-resistant tumors. The serum levels of PRL were measured by the RIA method. Abnormally high concentrations of PRL were found in 11/50 (22%) patients. Moreover, the percent of patients with cancer-related hyperprolactinemia was significantly higher in the hormone-resistant group than in the hormone-dependent group (8/15 vs 3/35, p<0.01). This study confirms the possible existence of a hyperprolactinemic state in metastatic prostate cancer, as previously reported by other authors. Moreover, it appears to demonstrate that the occurrence of hyperprolactinemia is more frequent in hormone-resistant neoplasms, suggesting the possible involvement of PRL in hormone independence. Further studies concomitantly evaluating PRL and chromogranin A blood concentrations will be necessary to establish whether the hyperprolactinemia precedes and promotes the onset of hormone resistance in prostate cancer, or whether it is simply a consequence of the hormone independence.

Abstract
Recently, the cohort of men from the European Male Ageing Study has been stratified into different categories distinguishing primary, secondary and compensated hypogonadism. A similar classification has not yet been applied to the infertile population. We performed a cross-sectional study enrolling 786 consecutive Caucasian-European infertile men segregated into eugonadal [normal serum total testosterone (≥3.03 ng/mL) and normal luteinizing hormone (≤9.4 mU/mL)], secondary (low total testosterone, low/normal luteinizing hormone), primary (low total testosterone, elevated luteinizing hormone) and compensated hypogonadism (normal total testosterone; elevated luteinizing hormone). In this cross-sectional study, logistic regression models tested the association between semen parameters, clinical characteristics and the defined gonadal status. Eugonadism, secondary, primary and compensated hypogonadism were found in 80, 15, 2, and 3% of men respectively. Secondary hypogonadal men were at highest risk for obesity [OR (95% CI): 3.48 (1.98-6.01)]. Primary hypogonadal men were those at highest risk for azoospermia [24.54 (6.39-161.39)] and testicular volume <15 mL [12.80 (3.40-83.26)]. Compensated had a similar profile to primary hypogonadal men, while their risk of azoospermia [5.31 (2.25-13.10)] and small testicular volume [8.04 (3.17-24.66)] was lower. The risk of small testicular volume [1.52 (1.01-2.33)] and azoospermia [1.76 (1.09-2.82)] was increased, although in a milder fashion, in secondary hypogonadal men as well. Overall, primary and compensated hypogonadism depicted the worst clinical picture in terms of impaired fertility. Although not specifically designed for infertile men, European Male Ageing Study categories might serve as a clinical stratification tool even in this setting.

Abstract
BACKGROUND Premature luteinization of one or more developing follicles complicates 1-2 % of controlled ovarian stimulation cycles for assisted reproduction. The management of this complication is controversial, with cycle cancellation likely representing the most commonly used strategy. The aim of this study was to evaluate the efficacy of the "freeze-all" policy-where the entire cohort of blastocysts is cryopreserved for subsequent frozen-thawed embryo transfer-in treating cases of premature luteinization. METHODS Patients experiencing premature luteinization during controlled ovarian stimulation-identified by extremely high progesterone levels at induction (P levels ≥3.0 ng/ml and/or P/estradiol ratio ≥1, n = 42)-were included in a "freeze-all" program and compared to controls undergoing a "freeze-all" program with normal progesterone levels at induction (P < 1.5 ng/ml, n = 67). RESULTS Blastulation rate was comparable between patients with premature luteinization and controls (48.1 ± 20.5 % in Cases vs. 52.3 ± 24.9 % in Controls, p = 0.36). Ongoing pregnancy rates after the first frozen-thawed embryo transfer (38.1 % in Cases and 41.0 % in Controls, p = 0.83) and cumulative ongoing pregnancy rates after three frozen-thawed embryo transfer cycles (40.5 % in Cases vs. 47.8 % in Controls, p = 0.55) were also similar. CONCLUSIONS These results show that extremely marked progesterone elevation throughout controlled ovarian stimulation does not impair blastocyst development and implantation potential in the context of a "freeze-all" strategy. Based on this, adoption of the "freeze-all" strategy represents a valuable tool in treating premature luteinization. In contrast, cycle cancellation-likely the most frequently used method for management of this complication-currently represents a misconduct.

Abstract
OBJECTIVE Cohort and case-control studies have suggested that adult physical activity (PA) may lower endometriosis risk and improve symptoms, but evidence is still controversial. To add information on leisure and occupational PA impact, if any, on endometriosis risk, we have analyzed data from a small case-control study conducted in Milan (Italy). STUDY DESIGN Ninety cases and 90 controls (median age 35 years, range 18-76) were compared. Endometriosis was laparoscopically diagnosed within the year before interview. Information on demographic variables, menstrual and reproductive history, occupational and recreational physical activity was collected. RESULTS A consistent protective effect emerged between leisure PA and endometriosis risk. For <2-4 and ≥5h/week (reference no PA), the estimated odds ratios (ORs) were, respectively: 0.36 (95% CI 0.18-0.74) and 0.83 (95% CI 0.27-2.53) as regards PA in early adolescence; 0.31 (95% CI 0.15-0.63) and 0.78 (95% CI 0.25-2.38) as regards PA in teenage years; 0.34 (95% CI 0.12-0.94) and 0.33 (95% CI 0.08-1.28) for PA in adulthood. However, no significant trend was seen according to hours spent in leisure PA. Occupational PA did not show statistical significant differences among different types or across age classes. CONCLUSIONS These results suggest that leisure PA in early adolescence, teenage years and adulthood may, to some extent, decrease the risk of endometriosis. In the interpretation of these results, however, the role of potential biases cannot be totally ruled out.

Abstract
BACKGROUND Clinical data suggest that the presence of an ovarian endometrioma may cause per se damage to the surrounding otherwise healthy ovarian tissue. However, the basic research has so far done a limited job in trying to understand the potential detrimental effect of an endometrioma presence in the context of the ovarian physiology. We have reviewed the literature with the aim of characterizing the pathophysiology of the endometrioma focusing mostly on factors and mechanisms potentially affecting the surrounding, otherwise normal, ovarian tissue. METHODS Comprehensive searches of PUBMED were conducted to identify human studies published from 1991 to 2013 in the English language on the cellular and molecular characterization of the various endometrioma components. RESULTS An endometrioma contains free iron, reactive oxygen species (ROS), proteolytic enzymes and inflammatory molecules in concentrations from tens to hundreds of times higher than those present in peripheral blood or in other types of benign cysts. The cyst fluid causes substantial changes in the endometriotic cells that it baths from gene expression modifications to genetic mutations The physical barrier between the cyst contents and the normal ovarian tissue is a thin wall composed of the ovarian cortex itself or fibroreactive tissue. ROS potentially permeating the surrounding tissues and proteolytic substances degrading the adjacent areas are likely to cause the substitution of normal ovarian cortical tissue with fibrous tissue in which the cortex-specific stroma is reduced. The fibrosis is associated with smooth muscle metaplasia and followed by follicular loss and intraovarian vascular injury. Follicular density in tissue surrounding the endometriotic cyst was consistently shown to be significantly lower than in healthy ovaries but this pathological change does not appear to be caused by the stretching of surrounding tissues owing to the presence of a cyst. CONCLUSIONS There is sufficient molecular, histological and morphological evidence, in part deriving from knowledge of the pathophysiology, to support a deleterious effect of the endometrioma on the adjacent ovarian cortical tissue, independent of the mere mechanical stretching owing to its size.

Abstract
BACKGROUND Patient safety within healthcare systems is a central aspect of health policy in most developed countries. From April 2007 to May 2009, the pilot project ExpIR-RO tested a voluntary incident reporting system in a public hospital in Bucharest Romania, in collaboration with two Italian hospitals (in Genoa and Milan). METHODS Data were collected anonymously through a form based on the Australian Incident Monitoring System. After appropriate training in reporting adverse events (AEs), staff in the participating Departments voluntarily completed the form. The study lasted 12 months in the Bucharest and Genoa hospitals and 3 months in the Milan hospital. Frequency distributions of replies and AE rates per 1,000 hospitalization days per month were assessed. RESULTS Overall, 185 AEs were reported (58 in Bucharest, 75 in Genoa and 52 in Milan). The corresponding rates (per 1,000 hospitalization days per month) were 1 in Bucharest, 3 in Genoa and 15 in Milan. Most AEs were related to diagnostic (28%) and surgical (14%) procedures and patient falls (12%) in Bucharest; patient falls (32%), nursing care (20%) and diagnostic procedures (19%) in Genoa; and nursing care (25%), drug prescription/administration (21%) and diagnostic procedures (17%) in Milan. Seventy-three per cent of respondents in Bucharest informed the patient of the AE, versus 64% in Genoa and 43% in Milan. Conversely, 75% of respondents in Genoa entered AEs in medical records versus 53% in Bucharest and 36% in Milan. CONCLUSION ExpIR-RO experience suggests that incident reporting could be introduced on a larger scale in Romania.

Abstract
The distribution of the different subtypes of HIV varies from one region of the world to another. Subtype B is predominant in Europe and the USA, but there has been a gradual increase in non-B subtypes as a result of migration from regions where they are endemic, and this may have important implications for the control of HIV-1. The aim of this study was to assess the prevalence of HIV-1 subtypes in an urban area of northern Italy in the period 1997-2008. Forty-nine (12.2%; 95% CI, 9.00-15.40) of 401 patients investigated carried a non-B subtype, the prevalence of which was 7.7% (95% CI, 4.96-10.44) among native Italians and 55.3% (95% CI, 39.49-71.11) among non-Italians, 1.6% (95% CI, 0.00-3.81) among ex-intravenous drug addicts, 7.6% (95% CI, 1.21-13.99) among homosexual/bisexual men and 20.5% (95% CI, 14.83-26.17) among heterosexuals, 6.8% (95% CI, 3.37-10.23) among Italians infected as a result of sexual contacts in Italy, and 55.0% (95% CI, 33.20-76.80) among Italians infected abroad or by foreign partners. Overall prevalence increased from 2.9% (95% CI, 0.00-6.11) before 1993 to 23.0% (95% CI, 16.31-29.69) in the period 2001-2008. The results demonstrate that there has been an increase in non-B subtypes (especially sexually transmitted infections), particularly among patients infected abroad or by foreign partners.

Abstract
Bacterial infections are the most frequent cause of hospitalization in elderly patients. In the early eighties, the advantages of Outpatient parenteral Antibiotic therapy (OPAT) were identified in the United States, and suitable therapeutic programs were established. In order to understand the different ways of managing OPAT, a National OPAT Registry was set up in 2003 in Italy. This study analyzes data concerning bacterial infections in 176 elderly patients including demographics, therapeutic management, clinical response, and side-effects. Bone and joint infections (48.9%) and skin and soft tissue infections (27.8%) were the most common infections treated with OPAT. Teicoplanin (28.9%) and ceftriaxone (22.1%) were the top two antibiotics chosen. OPAT was mainly performed at a hospital infusion center (52.8%). The clinical success rate was high and side-effects were low (12.6% of cases). Management of bacterial infections in the elderly with an outpatient program is effective and safe.

Abstract
BACKGROUND Surgery is often considered the best treatment option in women with symptomatic endometriosis. However, extent and duration of the therapeutic benefit are still poorly defined. METHODS The best available evidence on surgery for endometriosis-associated pain has been reviewed to estimate the effect size of interventions in the most frequently encountered clinical conditions. RESULTS Methodological drawbacks limit considerably the validity of observational, non-comparative studies on the effect of laparoscopy for stage I-IV disease. As indicated by the results of three RCTs, the absolute benefit increase of destruction of lesions compared with diagnostic only operation in terms of proportion of women reporting pain relief was between 30% and 40% after short follow-up periods. The effect size tended to decrease with time and the re-operation rate, based on long-term follow-up studies, was as high as 50%. In most case series on excisional surgery for rectovaginal endometriosis, substantial short-term pain relief was experienced by approximately 70-80% of the subjects who continued the study. However, at 1 year follow-up, approximately 50% of the women needed analgesics or hormonal treatments. Major complications were observed in 3-10% of the patients. Medium-term recurrence of lesions was observed in approximately 20% of the cases, and around 25% of the women underwent repetitive surgery. CONCLUSIONS Pain recurrence and re-operation rates after conservative surgery for symptomatic endometriosis are high and probably underestimated. Clinicians and patients should be aware that the expected benefit is operator-dependent.

Abstract
Myelolipoma of the adrenal gland is a benign, endocrinologically inactive neoplasm composed of mature adipose tissue and a variable amount of hematopoietic elements. Rarely giant adrenal myelolipomas have been reported in literature and they are very unusual clinical entities. We describe a case in a 72 year-old woman observed at our Department of Urology for nausea, flank and abdominal pain. The surgical resected mass measured 16.5x11.5x10 cm and weighted 1 250 g. A survey of the literature on this topic is made.

Abstract
BACKGROUND If the menstrual reflux or implantation theory of endometriosis is true, refluxed endometrial cells could reach the right hypochondrium transported by the clockwise peritoneal fluid current and would implant more easily on the right diaphragmatic leaf as they are stuck there by the falciform ligament. METHODS To investigate if a lateral asymmetry exists in diaphragmatic endometriotic lesion distribution, all articles on diaphragmatic endometriosis identified by MEDLINE, EMBASE and PUBMED database searches were retrieved, and additional reports were collected by systematically reviewing all references. The number of women and the side of the lesion with respect to the falciform ligament of the liver were obtained from individual studies, and the combined frequency of right- and left-side diaphragmatic endometriosis was computed. In addition, seven personal cases were described. RESULTS There were 16 reports including 47 subjects selected. Diaphragmatic endometriosis was on the right side in 31 (66%) patients, on the left in 3 (6%) and bilateral in 13 (27%). In the personal series, lesions were on the right side in five cases, on the left in one and bilateral in one. Considering only unilateral lesions, the observed proportion of right-sided endometriotic implants (36/40) was 90% (95% CI 76-97%; chi(2)(1) 32.6, P < 0.0001). CONCLUSIONS The observed major asymmetry in diaphragmatic endometriotic lesion distribution in favour of the right leaf supports the menstrual reflux theory.

Abstract
Cell motility and invasion are crucial events for endometrial cells, not only for the establishment of pathological states but also during the physiological tissue remodelling that occurs during the menstrual cycle and embryo implantation. We have characterized these phenomena in endometrial stromal cells evaluating cell migration-specific stimuli and the biochemical pathways involved. Ability of endometrial cells to migrate on collagen type IV substrate was evaluated by means of chemotaxis experiments. Modulation of this phenomenon by different growth factors and steroid hormones and their ability to activate extracellular signal-regulated protein kinase (ERK) and phosphatidylinositol 3 kinase (PI3K)/Akt signalling in this context were examined. Platelet-derived growth factor (PDGF)-BB, epidermal growth factor and fibroblast growth factor-2 as chemoattractant agents stimulated basal migration of endometrial stromal cells through the rapid activation of both ERK1/2 and PI3K/Akt signalling pathways. Experiments using wortmannin and PD98059, specific inhibitors of the PI3K/Akt and ERK1/2 activity, respectively, showed that the activation of both pathways is required for growth-factor-induced cell motility responses. Similarly, 17beta-estradiol (10(-6)-10(-8) M) could enhance both constitutive and PDGF-induced migration of the cells and their rapid treatment with the hormone significantly increased phosphorylation of ERK1/2 and Akt. Conversely, progesterone did not interfere with the basal migration but inhibits the PDGF-induced motility of this cell type. Rapid activation of intracellular signalling cascades ERK1/2 and PI3K/Akt by growth factors and estrogens is involved in the migration of normal endometrial stromal cells.

Abstract
We performed a MEDLINE and EMBASE search to identify all studies published in the English language literature on the use of progestogens for the treatment of endometriosis. The aim of our review was to clarify the biological rationale for treatment and define the drugs that can be used. It has been demonstrated that progestogens may prevent implantation and growth of regurgitated endometrium by inhibiting the expression of matrix metalloproteinases and angiogenesis, and they have several anti-inflammatory in vitro and in vivo effects that may reduce the inflammatory state generated by the metabolic activity of the ectopic endometrium. Oral contraceptives increase the abnormally low apoptotic activity of the endometrium of patients with endometriosis. Moreover, anovulation, decidualization, amenorrhoea and the establishment of a steady estrogen-progestogen milieu contribute to disease quiescence. Progestogens are able to control pain symptoms in approximately three out of four women with endometriosi. Different compounds can be administered by the oral, intramuscular, subcutaneous, intravaginal or intrauterine route, each with specific advantages or disadvantages. Medical treatment plays a role in the therapeutic strategy only if administered over a prolonged period of time. Given their good tolerability, minor metabolic effects and low cost, progestogens must therefore be considered drugs of choice and are currently the only safe and economic alternative to surgery. However, their contraceptive effectiveness limits their use to women who do not wish to have children in the short-term.

Abstract
BACKGROUND Urocortin (UCN) gene expression and synthesis have been reported in epithelial and stromal cells of the human endometrium. In this study we evaluated (i) UCN messenger RNA (mRNA) expression and peptide production in uterine specimens collected throughout the endometrial cycle, (ii) UCN secretion after decidualization of cultured human endometrial stromal cells (HESCs) and (iii) the effect of UCN on endometrial decidualization. METHODS HESCs were isolated from samples of human endometrium collected from healthy patients with normal menstrual cycle and cultured in presence of cAMP, 17-beta-estradiol (E(2)) + medroxyprogesterone acetate (MPA) and UCN. UCN levels were measured in endometrial extracts by an enzyme immunoassay, and changes of endometrial UCN mRNA expression were measured by RT-PCR analysis. RESULTS UCN peptide concentrations and mRNA expression were highest in the secretory phase of the menstrual cycle (P < 0.001, late secretory versus early and late proliferative phase) and higher in the late than the early secretory phase (P < 0.01). After decidualization of HESC with cAMP or E(2) + MPA, UCN levels rose in parallel with prolactin concentrations by days 6 (P < 0.01, for all). Finally, the addition of UCN to HESCs, with or without E(2) + MPA, induced the release of prolactin. CONCLUSIONS The evidence that (i) UCN is highly expressed in the secretory phase of the endometrial cycle; (ii) cAMP and E(2) + MPA modulate secretion of UCN and (iii) UCN induces HESCs decidualization together suggest a possible role for UCN in endometrial physiology.

Abstract
Splenic artero-venous fistula (SAVF) is a rare but potentially curable cause of pre-hepatic portal hypertension. About 100 cases have been reported in the world medical literature. The Authors report a case of 46-year-old man with a splenic artery aneurysm and a large SAVF treated by surgical resection of splenic vessels and splenectomy. The literature about SAVF is reviewed to recognize etiology, anatomical location, main symptoms at presentation, diagnostic findings and management of this rare syndrome.

Abstract
The human uterine mucosa of early pregnancy is largely populated by CD56(bright) natural killer (NK) cells (uterine (u) NK cells). The specific functions of these cells are still unknown, but their interaction and response to foetal trophoblasts are thought to be important for the establishment of a successful pregnancy. The study reported herein shows that uNK cells respond to, and produce, macrophage migration inhibitory factor (MIF), a cytokine highly expressed in the human placenta and in the cyclic and pregnant endometrium. Recombinant human MIF reduced in a dose-dependent manner the cytolytic activity of purified uNK cells against K562 cells. RT-PCR, Western blot analysis and ELISA demonstrated the synthesis and secretion of the cytokine by uNK cells. Double immunofluorescence staining showed the presence of MIF in uterine CD56 + cells. Finally, neutralization of the endogenous cytokine by a polyclonal antibody resulted in a sharp increase in the cytolytic activity of uNK cells. These findings indicate the existence of a previously unrevealed paracrine and autocrine action of MIF on uNK cells and support its contribution to the immune privilege at the maternal-foetal interface.

Abstract
In addition to its calciotropic function, the secosteroid 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)), has potent anti-proliferative/immunomodulatory effects on various tissues. Consistently, the enzyme that catalyzes the synthesis of 1,25(OH)(2)D(3), 1alpha-hydroxylase (1alpha-OHase) and the vitamin D receptor have a widespread tissue distribution. Among site-specific functions, the hormone has been suggested to be involved in uterine physiology. However, molecular analysis of the vitamin D system in normal endometrium throughout the menstrual cycle as well as its regulation in the context of endometrial physiological and pathological events have received very limited attention. Thus, we have studied expression, localization and regulation of 1alpha-OHase in human cycling and early pregnant endometrium. The capacity for 1alpha-hydroxylation and the presence of vitamin D receptor in endometrial cells have also been evaluated. The functional significance of these findings has been tested by evaluating gene expression of the catabolic enzyme, vitamin D 24-hydroxylase, and of the adhesion protein, osteopontin. Finally, to verify any potential dysfunction of the vitamin D system in endometriosis, a reproductive disease characterized by immune-mediated anomalies, we have analyzed expression of 1alpha-OHase in both eutopic and ectopic endometrium of affected patients. Results obtained showed that the active form of the 1alpha-OHase gene was expressed in human endometrial stromal cells independent of the cycle phase but with a significant increase in early pregnant decidua. A similar profile was observed for the protein, which was abundantly expressed in the cytoplasm of both endometrial stroma and epithelial glands. Both cycling and early pregnant endometrial cells also expressed the vitamin D receptor. In the same cells, 1alpha-OHase mRNA levels were significantly stimulated by the pro-inflammatory cytokine interleukin (IL)-1beta (50 and 500 pg/ml) while addition of the active form of the hormone could modulate both CYP24 and osteopontin gene expression. The 1alpha-OHase gene was also expressed in ectopic endometrium and its levels were increased in proliferative phase cultures derived from patients with endometriosis. Human cycling endometrium may be included among the extrarenal sites able to synthesize vitamin D. The IL-1beta-mediated induction of 1alpha-OHase gene and the hormonal modulation of osteopontin support a role for the hormone in the immunological mechanisms underlying uterine function. Abnormalities of this system are present in endometriosis.

Abstract
Hepatitis C virus (HCV) variability is mainly attributed to the ability of the virus to respond to host immune pressure, acting as a driving force for the evolution of quasispecies. This study was aimed at studying the changes in HVR-1 heterogeneity and the evolution of HCV quasispecies in HIV/HCV-coinfected patients according to the pattern of response to highly active antiretroviral therapy (HAART). Sixteen HIV/HCV-coinfected patients harbouring HCV genotype 1 and who had been on HAART for at least 1 year, 8 showing increasing CD4+T-cell counts (immunological responders) and 8 showing a stable or decreasing CD4+ T-cell counts (immunological non-responders), were selected from a prospective cohort study. After 1 year of HAART, 11 patients showed HIV viral load <2.6 log10 cp/ml (virological responders), and 5 showed HIV viral load above this value (virological non-responders). Plasma samples, collected before starting therapy and after 1 year of HAART, underwent clonal sequence analysis for HVR-1 region of HCV. Non-synonymous/synonymous substitutions ratio (Ka/Ks), aminoacidic complexity (normalized Shannon entropy) and diversity (p-distance), were considered as parameters of quasispecies heterogeneity. After 1 year of HAART, heterogeneity of HVR-1 quasispecies significantly decreased in virological non-responders, whereas the heterogeneity tended to increase in virological responders. The differences in the evolution were less stringent, when considering immunological response. On the other hand, profound qualitative modifications of HVR-1 quasispecies were observed only in patients with both immunological and virological HAART response. On the whole, these findings suggest that, in patients undergoing HAART, the extent of HCV variability and the evolution of HVR-1 quasispecies is influenced by the pattern of response to antiretroviral therapy.

Abstract
UNLABELLED Endometriosis is a multifactorial disease that can affect up to 10-15% of women in their reproductive age. Epidemiological studies indicate that it is a polygenic disorder with recurrence risks in first-degree relatives of about 5-7%. Thus, the present aim of different research groups is to identify genetic variations in obvious candidate gene that could be associated with an increased susceptibility to endometriosis. The great advancement in molecular biology techniques make this task certainly possible, although particular attention needs to be paid to the study design in order to achieve reliable RESULTS The data obtained by such studies will allow to expand our knowledge on the pathogenesis of the disease and, more importantly, to develop individualized therapies and prevention strategies to apply at high-risk populations.

Abstract
The hormone resistance of prostate cancer has been proved to depend at least in part on enhanced neuroendocrine activity and the resultant increase in blood concentrations of chromogranin A. Other experimental observations have suggested the involvement of prolactin (PRL), which appears to be a potential growth factor for prostate cancer. Abnormally high levels of PRL have been detected in metastatic prostate cancer, but the clinical significance of this finding has still to be clarified. In an attempt to explain the prognostic significance of serum PRL levels in prostate cancer, in this preliminary study we have analyzed the PRL levels in a group of metastatic prostate cancer patients with hormone-dependent or hormone-resistant cancer. The study included 50 patients with metastatic prostate cancer, 15 of whom had hormone-resistant tumors. The serum levels of PRL were measured by the RIA method. Abnormally high concentrations of PRL were found in 11/50 (22%) patients. Moreover, the percent of patients with cancer-related hyperprolactinemia was significantly higher in the hormone-resistant group than in the hormone-dependent group (8/15 vs 3/35, p < 0.01). This study confirms the possible existence of a hyperprolactinemic state in metastatic prostate cancer, as previously reported by other authors. Moreover, it appears to demonstrate that the occurrence of hyperprolactinemia is more frequent in hormone-resistant neoplasms, suggesting the possible involvement of PRL in hormone independence. Further studies concomitantly evaluating PRL and chromogranin A blood concentrations will be necessary to establish whether the hyperprolactinemia precedes and promotes the onset of hormone resistance in prostate cancer, or whether it is simply a consequence of the hormone independence.

Abstract
Background Chronic hepatitis C is common and aggressive in HIV-positive patients, so the development of a well-tolerated HCV therapy is a priority. We evaluated the efficacy and safety of pegylated interferon α2b (PEG-IFN) plus ribavirin (RBV) versus PEG-IFN monotherapy in HIV/HCV-coinfected patients undergoing highly active antiretroviral therapy (HAART), and analysed the predictive factors of response. Methods An Italian, multicentre, open-label trial including 135 coinfected patients, randomized to PEG-IFN 1.5 μg/kg/week plus RBV 400 mg twice daily ( n=69, arm A) or PEG-IFN 1.5 μg/kg/week ( n=66, arm B) for 48 weeks. We assessed the predictive values of early virological response (EVR) at week 8 (HCV-RNA drop >2 log10 compared with baseline or undetectable levels) on sustained virological response (SVR). Results Fifty-five patients (28 from arm A and 27 from arm B) completed 48 weeks of therapy. At the end of treatment, 20/28 patients in arm A and 11/27 in arm B had HCV-RNA <50 IU/ml. In a per-protocol analysis, SVR was reached by 54% of patients in arm A (genotype 2–3, 11/16; genotype 1–4, 4/12) and 22% in arm B (genotype 2–3, 3/15; genotype 1–4, 3/12). In an intention-to-treat analysis, the SVR was 22% in arm A (genotype 2–3, 11/32; genotype 1–4, 4/37) versus 9% in arm B (genotype 2–3, 3/32; genotype 1–4, 3/34). The best predictors of SVR were the use of combination therapy, infection with HCV genotype 3 versus genotype 1, and EVR at week 8. Thirty patients (15 from arm A and 15 from arm B) dropped out of the trial prematurely due to side effects. The positive predictive value of EVR at week 8 was 65%, the negative predictive value was 86%. Conclusions PEG-IFN plus RBV can be considered a solid option for the treatment of HIV/HCV-coinfected patients. The key to successfully improving efficacy is strong compliance through strict overall patient monitoring, in order to best manage drug toxicity. EVR assessment at week 8 may become a useful stategy in the management of therapy.

Abstract
The prognostic role of GB virus type C (GBV-C) viraemia in HIV-infected subjects treated with highly active antiretroviral therapy (HAART) is still undefined, The aim of this analysis is to assess the relationship between GBV-C infection and response to antiretroviral therapy among HIV-infected subjects initiating HAART when antiretroviral-naive. A prospective, observational study of 400 HIV-infected patients with measurements of GBV-C RNA, hepatitis C virus (HCV) antibodies and HCV RNA determined from plasma stored prior to HAART initiation, Time to virological (achieving HIV RNA ≤500 copies/ml) and immunological success (a CD4+ count increase of ≥200cells/μl), and the time to virological relapse (confirmed HIV RNA >500 copies/ml) were assessed by Kaplan-Meier methods and Cox proportional hazard regression model. Of the subjects, 117 (29.3%) were GBV-C positive and, overall, 351 (87.8%) patients achieved virological success, After controlling for a number of confounders including HCV RNA, GBV-C viraemic patients experienced a significantly lower risk of HIV rebound than those who were GBV-C negative [relative hazard (RH)=0.56, 95% CI: 0.34–0.93, P=0.03], Conversely, the probability of achieving initial virological success or CD4+ count response after HAART did not differ between GBV-C-negative and -positive subjects, These results suggest that GBV-C coinfection may play a role in determining the rate of HIV rebound possibly by competing with HIV replication after HIV load has been successfully suppressed by HAART.

Abstract
OBJECTIVES To evaluate the risk factors for lopinavir/ritonavir (LPV/r)-related liver enzyme elevation (LEE) in HIV antiretroviral-experienced patients. METHODS An open prospective observational study was carried out to analyse the incidence and time of LEE development during LPV/r treatment, and to determine whether LEE development was correlated with epidemiological, clinical and biochemical data, immune and virological profiles, concomitant hepatic diseases, antiretroviral therapy, or histological and ultrasonography liver examination results. A diagnosis of LEE was considered when LEE symptoms occurred after LPV/r introduction and was confirmed by a second control within 2 weeks. RESULTS A total of 782 HIV-positive outpatients have been enrolled in six different Infectious Diseases Departments in Northern Italy since August 2000. Of these patients, 71 (9.1%) developed LEE within 115+/-85 days (mean+/-standard deviation); 13 of these subjects discontinued LPV/r and four were hospitalized. Of the patients with LEE, 74.6% and 25.4% had grade 2 and > or =3 toxicity, respectively. No correlation between LEE and sex, baseline CD4 cell count, viral load, HIV stage, triglyceride values, histological and ultrasonography liver examination results, nevirapine use, or increase in CD4 cell count was observed. Higher baseline alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) values (P < 0.0001 and P=0.004, respectively), younger age (P=0.008), previous hepatitis B virus (HBV) infection (P=0.012), efavirenz use (P=0.04), and hepatitis C virus (HCV) and/or HBV coinfection (P < 0.0001, relative risk 4.78) were significantly related to LEE. No correlations between LEE and the same risk factors as investigated in the whole study population were found in subgroups of patients with HCV and/or HBV infection. CONCLUSIONS HCV and HBV testing and measurement of baseline ALT values are essential for screening subjects at risk of LEE before starting LPV/r. Strict monitoring of clinical and biochemical parameters should be performed in these patients.

Abstract
Endometriosis is a benign gynaecologic disease that is associated with a certain risk for malignant degeneration. The disease has a genetic background, but the locations of possible genomic aberrations are still poorly clarified. In this context, the proline form of TP53 codon 72 polymorphism has been recently associated with the risk of developing endometriosis. In this case-control study, we aimed to investigate further the potential association between endometriosis and this polymorphism in order to evaluate whether this genetic variant may influence the susceptibility to the disease. Genomic DNA was obtained from a consecutive series of 303 Italian Caucasian women of reproductive age who underwent laparoscopy for benign gynaecological pathologies. Endometriosis was defined according to the criteria of Holt and Weiss [Holt V and Weiss NS (2000) Recommendations for the design of epidemiologic studies of endometriosis. Epidemiol 11,654-659] for the definite disease. Subjects of similar age without laparoscopic evidence of the disease served as control group. Molecular analysis of TP53 codon 72 polymorphism was performed by PCR amplification. Endometriosis was documented in 151 women. We found no statistically significant difference in the distribution of TP53 codon 72 polymorphism genotypes between patients with and without endometriosis. The respective proportions of arginine homozygotes, heterozygotes and proline homozygotes were 55.6, 39.7 and 4.6% in the group with endometriosis and 59.9, 30.9 and 9.2% in the control group. Moreover, no statistically significant association was demonstrated between TP53 codon 72 polymorphism and the various clinical manifestations of the disease, although a non-significant tendency towards an increased frequency of the proline allele was observed in association with specific manifestations of the disease reflecting a more severe form. Our results suggest that the TP53 codon 72 polymorphism does not confer genetic susceptibility to endometriosis in the Italian population. However, a possible susceptibility role of this polymorphism in endometriosis development towards very severe forms cannot be ruled out.
